Apple 45W MagSafe Power Adapter for MacBook Air

Apple 45W MagSafe Power Adapter for MacBook Air

Overview

The 45-Watt MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.

When the connection is secure, an LED located at the head of the DC connector will light; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives users an even easier and more compact way to travel.

Redesigned specifically for MacBook Air, the adapter is the perfect traveling companion. It has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.

This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.

Compatible only with MacBook Air with MagSafe Power Port.

Not sure if this is the right power adapter for your Mac?

Knowing which specific Mac model you have is important. If you are running OS X Lion (10.7) or later go to the “” menu at the top left of your screen, choose “About this Mac” then click the “More Info...” button. Your Mac model and generation will be displayed.

If you are running an earlier version of OS X, you can enter your serial number here to find out which model you have.

Works Fine - BUT PRICE IS RIDICULOUS

I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power adapter on mine works just fine ... no problems. Instead of unplugging every time I hit the road, I thought it would be a good idea to buy a spare for my computer bag. Wrong!
$79.95? Is this someone's idea of a joke? Eighty bucks for a power adapter? Sure the cell phone manufacturers have run this scam for years, refusing to standardize on a plug configurations/power ratings so that the buyer is forced to buy yet another power adapter (I've got about twenty of them sitting in a drawer). But those pieces of junk are only $20 or $30. $80? For what?
I've got AppleCare, so I'll just keep on plugging in and unplugging the one adapter I have until it dies, then you can replace it for free. Really, you folks at Apple build the coolest stuff on earth, but you do need to re-think your policy of over-charging for the small stuff.

I'm a new Apple person, love the MacBook Air! But the power supply is already intermittent. It is under warranty, but they will not pay me for the half-day I will spend going to the Apple store to get something that should last longer than the computer!

I went through college with a MacBook Pro and the MacBook Air was my first large purchase with Apple since I have graduated college and have been working full-time.
I am so beyond disappointed that I am on the verge of getting rid of it. The chragers are the biggest headache and absolutely cheap. This adapter makes the entire computer junk. The quality is SO cheap in comparison to the Pro and it is so ridiculous. Run away from this disgustingly poor quality cord.

This is my 4th MagSafe power adapter, and each has failed for the same reason: the rubber coating near the metal end just falls apart even though the cable has been treated with kid gloves. Very frustrating and disappointing for a premium-priced accessory.

0 Stars! I've had to buy a new adapter EVERY.SINGLE.YEAR (if they even last a whole year)! Total rip-off. Great computers but Apple is way too Greedy to charge $80 for the charger/adapter. Must be a marketing scheme for more profit. Apple- you can charge half or 1/4 of the price for the charger and still make a ton of money!

Yes, the computer knows how much power to draw, and using an 85W adapter on your 13inch MBPro will be perfectly safe.

The white box is a built in power converter so you should be fine with plugging it in as long as you have the adapter that changes plug types. You can check to see if other things are converters if it has something like Input: 100-240V~1.5A 50-60Hz. This shows that an electric current of 100-240 Volts can power the converter without problem, which Spain's electricity falls in. If you cannot find this on a product (though most electronics made in about the last 5-10 years automatically convert) or if you feel you would rather side with caution you can but a converter, but only leave it plugged it when you need the power because converters burn out quickly from overheating if you leave them plugged in too long.

From Macworld Mag 2006:
If you hold the two power supplies side by side, you’ll notice that the MacBook Pro’s is larger. That’s because the MacBook Pro uses an 85-watt power supply, while the MacBook uses a 60-watt power supply. Apple says you can use the more powerful, 85-watt power supply with a MacBook without any problems, and that in 80 percent to 90 percent of situations, you can use the MacBook’s power supply with the more-demanding MacBook Pro as well. If you’re really taxing the MacBook Pro’s processor with some heavy-duty work, the MacBook’s adapter will still be able to power the MacBook Pro—but it may not have any power left over to charge its battery.
so, yes, contrary to what everyone else has said, you can.
